6 - PROBLEMS, MAINTENANCE AND GUARANTEE
6.1 - ERROR SIGNALLING
Error
Reason
Action
- - - -
Probe
interrupted
Verify the correct
connection between probe
and instrument and then
verify the correct
functioning of the probe
uuuu
The measured variable
is under the probe’s
limits (under-range)
oooo
The measured variable
is over the probe’s
limits (over-range)
ErAt
Auto-tuning
not
possible
Push key “P” in order to
make the error message
disappear. Once the error
has been found, try to
repeat the auto-tuning.
noAt
Auto-tuning not finished
within 12 hours
Check the functioning of
probe and actuator and
try to repeat the auto-
tuning.
ErEP
Possible anomaly of the
EEPROM memory
Push key “P”
In error conditions, the instrument provides an output power as
programmed on par “OPE” and activates the alarm, if the relative
parameter “AL1i” have been programmed = yES.
6.2 - CLEANING
We recommend cleaning of the instrument with a slightly wet cloth
using water and not abrasive cleaners or solvents which may
damage the instrument.
6.3 - WARRANTY AND REPAIRS
The instrument is under warranty against manufacturing flaws
or faulty material, that are found within 1
8
months from delivery
date. The warranty is limited to repairs or to the replacement
of the instrument. The eventual opening of the housing, the
violation of the instrument or the improper use and installation of
the product will bring about the immediate withdrawal of the
warranty’s effects.
In the event of a faulty instrument, either within the period
of warranty, or further to its expiry, please contact our
sales department to obtain authorisation for sending the
instrument to our company. The faulty product must be shipped to
Ascon Tecnologic with a detailed description of the faults found,
without any fees or charge for Ascon Tecnologic, except in the
event of alternative agreements.
